drivers/i2c/busses/i2c-ismt.c:770:2: error: case label does not reduce to an integer constant
case ISMT_SPGT_SPD_400K:
^~~~
drivers/i2c/busses/i2c-ismt.c:773:2: error: case label does not reduce to an integer constant
case ISMT_SPGT_SPD_1M:
^~~~
See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@xxxxxxx for the gory
